DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The present invention is directed to a portable toilet for marine craft. The preferred embodiment of the invention is depicted in FIGS. 1-4 and is generally referenced by numeral 10.

[0028] As diagrammatically illustrated in FIG. 1, a view of the portable toilet for marine craft is depicted in which a person P is shown using the portable toilet for marine craft 10, the portable toilet 10 being located on the deck of a conventional boat B. In recent years, boating has become an ever more popular form of recreation, providing endless hours of pleasure and leisure to millions of people. Nevertheless, a serious problem exists in that many boaters must endure inadequate restroom facilities, particularly on small and medium-sized watercraft. Families not infrequently find this discomfiting, particularly since the only option may be to resort to unsanitary methods which, since the decks of boats are fairly easily observed from afar, can involve significant privacy concerns.

[0029] Many previous attempts to provide a solution to the need for a practical and effective portable marine toilet 10 are unsatisfactory, because they require individuals to sit in uncomfortable positions, such as over the edge of a boat, or use ineffective privacy coverings such as sail-like curtains, which may be unwieldy under windy conditions. Additionally, ineffective sanitary means, such as those involving the direct discharge of sewage into the surrounding water or which do not effectively sterilize contaminated matter, present serious questions of cleanliness and reduce product appeal, and can even result in violations of state or federal law.

[0030] Marine sanitation devices are specially designed for use on pleasure craft, and are made to conform to Coast Guard standards regarding discharge of sewage into restricted waters. other benefits of portable marine toilets include the neutralization of odor causing molecules, and the disinfection of potentially hazardous matter. Space is limited on boats, and the space which is available is usually devoted to boat seats, navigational equipment, and storage areas or housing for fishing and boating accoutrements.

[0031] Another drawback of water craft and portable toilets is the fact that rough waves or rocking of the boat can make portable toilets potentially dangerous if they are unsecured, possibly resulting in their sliding across the deck and causing damage. Thus, if a device could be built which would maximize the efficient use of space on board, while providing an aesthetically pleasing and secure housing, an important contribution to the art would be made. The present invention provides an effective means by which a conventional portable toilet can be used on a boat by incorporating a boat seat into the protective housing of a portable toilet, providing a practical solution to this longfelt need.

[0032] Turning now to FIG. 2, it can be seen that the portable marine privacy toilet 10 comprises a substantially box-shaped housing 12 adapted for closely receiving a portable toilet therein so as to allow a user's legs to always be on the outside of the housing 12 to insure comfort. The toilet 10 also comprises a boat seat assembly 14, which includes a support structure or brace 16 for connecting the boat seat assembly 14 to the housing 12. The housing 12 preferably includes front 18, back 16, and lateral 20 side walls and a bottom 21, the walls each having a top portion 22 and lateral side edges, generally 24, and extending upwardly from the bottom 21. Each wall is joined to an adjacent wall at a lateral side edge 24 thereof by at least one fastener, each generally 26. Any fastening means commonly known in the art and in conventional usage can be employed to join the walls together including the angle brackets 25 shown, as well screws, pins, nails, angle irons, plates, bolts, and adhesive substances. Alternatively, the walls can be integrally formed together, the housing 12 comprising injection-molded plastic to form a one-piece structure.

[0033] The front wall 18 of the housing 12 preferably has a generally rectangular-shaped opening 27 disposed thereon for receiving the flush pedal or lever 28 therethrough of a portable toilet seat 30 and cover 32, although the opening 27 and flush pedal 28 can be absent in alternative embodiments. The housing 12 of the invention can be covered with a vinyl sleeve or liner (not shown) to match the seat 34 in an alternative embodiment of the invention. The housing 12 can be comprised of any substance, including polymeric material, metal, and wood, and can be designed according to any shape, size, appearance, and dimensions, according to the needs of the user and the specifications of the manufacturer.

[0034] Turning now to the exploded view of FIG. 4, the boat seat assembly 16 preferably includes a boat seat 34, a boat seat back 36, and a support brace 16 comprising first and second support members 38 and 40, respectively, hingedly connected together. The first support member 38 connects the boat seat back 36 to the second support member 40 with the hinge 42 allowing the seat back 36 to fold forwardly over, as shown in FIG. 3. The inner surface 44 of the generally L-shaped second support member 40, which is fixedly attached to the top 22 of the walls, defines a seat receiving portion for supportably and removably receiving the boat seat 34. The second support member 40 can also comprise a spacer element to allow the top of the portable toilet to protrude above the top edge 22 of the housing 12. It should be understood that the specification embraces configurations and designs for all boat seats 34, as well as conventional boat seat designs such as commonly known in the art.

[0035] The boat seat back 36 and boat seat 34 are preferably padded, comprising an inner support, and an exterior liner preferably made of waterproof polymeric material, such as polypropylene, polyvinyl chloride, or similar thermoplastic material. The housing 12 further comprises a fastener 46 for removably connecting the boat seat 34 to the housing 12 and a mating fastener 48 located on an underlying seat support rod 50. In the preferred embodiment of the invention, the fastener 48 is a hook and loop fastener, and is brought into abutting and reversibly connectible relationship with its mating fastener 46 by proper placement of the seat 34 on the housing 12. Any conventional fastener other than the hook and loop type can be used for attaching the boat seat to the top portions of the side walls or the housing, including adhesive materials, clips, snaps, and interlocking attachment devices.

[0036] Referring back to the exploded view in FIG. 3, the portable marine privacy toilet 10 can also have a swivel assembly 52 attached to the bottom 54 thereof for allowing the toilet 10 to be vertically pivotable. The swivel assembly can comprise any means for allowing the toilet 10 to be pivotable, including a rotatable bearing unit (not shown). In the preferred embodiment of the invention, this rotatable bearing unit would include upper and lower bearing plates, each comprising a ring-shaped depression which, when matched together, define a raceway for bearing balls. And although the toilet is portable, the housing 12 or swivel assembly 52 can include at least one fastener 31 for fastening the toilet 10 to an underlying or upstanding support surface.

[0037] The portable marine privacy toilet housing 12 further preferably comprises a pair of clamps 56 for removably fastening a privacy cover 58 to the toilet 10. The cover 58 comprises a main axis rod 60 having a plurality of U-shaped bales 62, movably fastened thereto, for supporting a covering portion 64 for concealing a person when using the toilet 10. The cover 58 can comprise any suitable material, but is preferably non-transparent, lightweight, and water resistant. The main axis rod 60 removably but securely fits into the clamps 56 as indicated by the ghost lines. The weight of the toilet 10 insures its stability when on deck, as well as the stability of the cover 58 which it is attached.

[0038] It should be understood that any jacket, shelter, enclosure, blind, or cover can be used, including covers that do not directly connect to the housing or are free standing. Also any kind of connector between the toilet and the cover can be used, the clamp 56 being a preferred embodiment of the connector. Nevertheless, as shown in FIG. 1, the preferred embodiment of the cover 58 herein described when positioned with the user forwardly facing into the wind, provides for decreased wind resistance and stability to the overall invention. Furthermore, it should be stressed that the present invention embraces any and all models of portable toilets 30 such as in conventional usage or commonly known, the housing 12 being suitably dimensioned or adaptable to receive them. Therefore, any boat seat incorporating or housing a toilet, especially a portable marine toilet, as well as any combination boat seat/toilet with or without a privacy cover is fully encompassed.
